Resolution Revert Takes 7000 Seconds?

Hey guys,

I've got a strange one here. I work for a small IT business that builds PC's for home consumer use. We have a standard computer build that we make and sell that performs fine. (Win 7 64 bit Pro,asus f1a55-m lx plus r2.0 mobo, AMD a8-5600k proc, Radeon HD 6000 onboard video).

We've built hundreds identical to this, but this morning I came across one that had a peculiar problem. Any time you go to change the monitor's resolution (on any monitor), the timer for it to revert back if it goes out of range is set at 7000 seconds (as opposed to the standard 30). I've never before come across something like this. I looked through every configuration setting known, and exhausted my google resources as well. I can't find anything at all on this subject.

Have any of you ever come across something like this? I've already made sure all drivers and updates are up to date, so I'm a bit stumped on this one.

I appreciate any help you could provide.

Thank you.
